4089 Galbraith           Discovered 1986 May 2 at Palomar.
Harvard University economist and polemicist John Kenneth Galbraith (1908-2006), renowned for his use of irony and for stressing the human element in the study of economics, rejected "the conventional wisdom" (a term introduced in his 1958 best-seller The Affluent Society) and the idea that economics is a "science".
